High-volume secure information delivery

In a mass production environment, such as one that generates
secured monthly invoices for a telecom company, creating licenses
that are specific to each document can become a resource-intensive
process. In such cases, document security supports the association
of licenses to users, rather than to the documents. The license
generated for a user is used for all documents that are protected
for that user.

One advantage of this approach is that the document security
database size doesn't grow linearly with the documents, rather with
the number of users. Also, because you need to create the license
only once for a user, subsequent protection of documents through
these policies becomes faster. Features such as offline access,
document expiration, and revocation are supported for all such documents.

Document security also supports Abstract Policies. Abstract policies
are policy templates that contain all policy attributes such as
document security settings and usage rights, but do not contain
a list of principals. Administrators can create any number of policies
from the abstract policy with different principals who should have
access to the documents. Changes made to the abstract policy do not
affect the actual policies that are generated from the abstract
policies.

In the case of monthly invoice generation for a telecom company,
you create an abstract policy, create users, and then generate unique
licenses for each user. The licenses are later applied to documents
for each user.

Creation of an abstract policy is supported only through document
security Java SDK. You can, however, administer the policies that
you create from the abstract policy from the document security web
pages. Policies that are created using this method are identical
in behavior to those created from document security web pages.
